Chancellor’s Colloquium on Evolution: Biology and Beyond

Just over 30 years ago, here at the University of Illinois, Carl Woese and colleagues set out to chart the evolutionary relationships or family tree, if you will, of living organisms. They made the groundbreaking discovery that there are three domains of cellular life, not two as had been previously thought. This discovery, and the way in which it was made, has transformed evolution into a quantitative, empirical science, and impacted biology in ways that are still unfolding. Part of the legacy of this pioneering work is the dramatic visualization of evolution in action through the so-called "Tree of Life", first constructed by Woese's team. As you view, perhaps for the first time, this remarkable construct of evolution in action, ask yourself: what does it really mean? Is this the record of a collection of unrelated historical accidents, a mere progression of forms? Or is there a dynamical process at work, which somehow reflects the complex interplay between organisms and their environment, between the genome and organismal characteristics, .and between the flows of energy and information? And is the evolutionary process one that is unique to organic life, or a reflection of deeper physical principles that might extend to other realms of knowledge?

The unprecedented public interest in evolution during 2009 is being driven by numerous special anniversaries: 150 years since the publication of the Charles Darwin’s Origin of Species; 200 years since the publication of Jean Baptiste de Lamarck’s Philosophie Zoologique, and 151 years since the first publication in a learned scientific journal of what has come to be known as the theory of natural selection, by Alfred Russel Wallace. But despite all that we have learned during the 19th and 20th centuries, what do we really understand about evolution today? Are the foundations of the subject now so well-understood that only incremental work remains to be done? And is evolution only a small, but highly controversial, arcane corner of biology, disconnected from the rest of scientific thought, and of primary interest only to theologians, school education boards, and philosophers of science?

The Chancellor's Colloquium on "Evolution: Biology and Beyond" is our way of bringing such fundamental and cross-cutting questions to the campus community during the forthcoming academic year. We have resisted the temptation to create a celebration that is backwards-looking, historical, and personality-focused, primarily because we believe that the fundamental characteristics of the evolutionary process have yet to be realized and, hence, a true science of biology-as-evolutionary process has yet to emerge. As new genomic tools illuminate the molecular mechanisms of evolution and the incredible dynamic interconnectedness that is biological organization in general, it is becoming all too apparent that our preconceptions about the fundamental nature of the evolutionary process need to be revised. At a time when society itself is challenged by such diverse threats as global climate change, pandemics, financial upheaval, and the shocking failure of trusted medicines such as antibiotics, it is more important than ever to try to understand the unifying framework behind these complex phenomena, one which we believe to be evolutionary in character.

We have called this series "Biology and Beyond", because it is becoming increasingly clear that evolutionary concepts are poised to encompass and impact communications and computer technology, sociology, medicine, and, unavoidably, the physical sciences. It is our express hope to involve the entire campus community, on both sides of Green Street, in these events. To this end, we have invited a small group of outstanding and unconventional thinkers to share with us their insights and perspectives on these and other questions. They represent an eclectic array of disciplines—indeed, one characteristic they all share in common is that their work eludes simple classification and traditional disciplinary boundaries—and together they consolidate what we already know and paint a picture of the future of evolution.

We are grateful to Chancellor Richard Herman and the Office of the Provost for giving us the chance to offer this gift to the campus. Without their appreciation of our vision and their support, this series would not exist. We are equally grateful to Harris Lewin and the Institute for Genomic Biology for its logistical support, with special thanks due to Debbie Piper and Melissa Edwards.

We hope you will join us during the coming year in what we are sure will be an exciting, stimulating, and energizing series of talks and discussions.
